All the parts must be cleaned before the part is examined. Refer to the Cleaning-000 TASK 79-21-43-100-400.

All parts must be visually examined for damage, corrosion and wear. Defects that are not identified in the procedure must be referred to IAE.

Do not discard the part until you are sure there are no repairs available. Refer to the instructions in Repair before a discarded part is used again or oversize parts are installed.

Parts which must be discarded can be held although no repair is available. The repair of a discarded part could be shown to be necessary at a later date.

All parts must be examined to make sure that all the repairs have been completed satisfactorily.

The practices and processes referred to in the procedure by the TASK/SUBTASK numbers are in the SPM.
